[0001] Cross-reference to Related Applications

[0002] This application claims priority to the Chinese Patent Application No. 202410537130.2, filed on April 29, 2024, and entitled "A communication method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the field of communication technology, and in particular, to a communication method and apparatus. BACKGROUND

[0004] In the process of the evolution of the 5th-generation (5G) mobile communication system to 5G-advanced (5G-A) technology, the communication and perception integration technology is considered as one of the key technologies that can expand the business capabilities of the mobile communication network. The core idea of the communication and perception integration technology is to add perception capabilities on the mobile communication network to build the ability to detect, track and image targets, so that the two capabilities of communication and perception can coexist in harmony and mutual benefit.

[0005] The principle of the perception technology is that the perception sending end device sends radio waves (i.e., perception signals) in a specific direction. When the radio waves irradiate the surface of the perception target, reflected waves (i.e., echo signals of the perception signals) are formed. Then, the perception receiving end device receives and processes the reflected waves to generate measurement quantities, and reports them to the perception sending end device. Based on the measurement quantities, the perception sending end device can obtain perception data, such as the position, speed or type of the perception target. Currently, how to improve the perception performance is an important research direction. SUMMARY

[0006] Embodiments of the present application provide a communication method and apparatus, which can obtain the processing capability of the perception receiving end device for the perception signals, and is beneficial to improving the perception performance.

For example, the first communication apparatus can be a network device, or can be a terminal device, which is not limited.

[0008] Taking the first communication device as an execution subject, the method comprises: the first communication device sending first information, the first information comprising information of a coherent processing interval supported by the first communication device and / or information of a cross-coherent processing interval supported by the first communication device, wherein the information of the coherent processing interval comprises a maximum time length of the coherent processing interval and / or a maximum number of time units included in the coherent processing interval, and the information of the cross-coherent processing interval comprises a maximum time length of the cross-coherent processing interval and / or a number of coherent processing intervals included in the cross-coherent processing interval; wherein the cross-coherent processing interval comprises M coherent processing intervals, and M is an integer greater than 1. For example, the first communication device sends the first information to a second communication device.

[0009] In the above embodiments, the first information sent by the first communication device comprises information of a coherent processing interval supported by the first communication device and / or information of a cross-coherent processing interval supported by the first communication device, so that other communication devices (for example, the second communication device) can determine the processing capability (for example, the processing capability for sensing signals) of the first communication device according to the first information, thereby being able to configure a coherent processing interval and / or a cross-coherent processing interval that conforms to the processing capability of the first communication device, which is beneficial to improving the sensing performance.

The first communication device supports associating processing of measurement quantities of multiple coherent processing intervals, which can obtain more coherent processing gain, and is beneficial to improving the sensing performance.

[0049] A network device is a network-side device with wireless transceiving function. The network device can be a device in a radio access network (RAN) that provides wireless communication function for a terminal device, referred to as a RAN device; or the network device can also be a core network device. For ease of understanding, the network device is taken as a RAN device in the following description. The RAN can be an access network in the 3rd generation partnership project (3GPP), for example, a 4G, 5G, or future-oriented 6G network. The RAN can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a communication network of two or more of the above networks. The RAN device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5G mobile communication system, a base station in a 6G mobile communication system, a base station in a future mobile communication system, an access node in a WiFi system, a wireless relay node, or a wireless backhaul node, etc.

[0050] The RAN device can also be a module or unit that completes the functions of the base station part, for example, can be a central unit (CU), can also be a distributed unit (DU), and can also be a radio unit (RU). The CU here completes the functions of the radio resource control protocol and the packet data convergence layer protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete part of the physical layer or all the physical layer functions. For specific descriptions of the above-mentioned various protocol layers, refer to the relevant technical specifications of the 3rd generation partnership project (3GPP). The CU and the DU can be separately arranged, or can also be included in the same network element, for example, in a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, for example, included in a remote radio unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH). In different systems, the CU, the DU, or the RU can also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, and the RU can also be referred to as an O-RU. Any one of the CU (or CU-CP, CU-UP), the DU, and the RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. The network device can be a macro base station (such as 110a in FIG. 1), can also be a micro base station or an indoor station (such as 110b in FIG. 1), and can also be a relay node or a donor node, etc. The embodiments of this application do not limit the specific technologies and specific device forms adopted by the network device.

[0051] In the embodiments of this application, the functions of the network device can also be executed by a module (such as a chip) in the network device, or can also be executed by a control subsystem containing the functions of the network device. The control subsystem containing the functions of the network device here can be a control center in the above-mentioned application scenarios such as smart grid, industrial control, intelligent transportation, and smart city.

[0052] The terminal device is a user-side device with wireless transceiving function. The terminal device can also be referred to as a terminal, a user equipment (UE), a user terminal, a user apparatus, a user unit, a user station, an access terminal, an access station, a UE station, a remote station, a wireless communication device, a mobile station, or a mobile terminal, etc. The terminal device can be widely applied in various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine to machine (M2M) or machine-type communication (MTC), internet of things (IOT), virtual reality (VR), augmented reality (AR), industrial control, self driving, remote medical, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiving function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc.

[0053] In the embodiments of the present application, the apparatus for implementing the function of the terminal device can be a terminal device, or an apparatus capable of supporting the terminal device to implement the function, such as a chip system or a combination device or component that can implement the function of the terminal device, which can be installed in the terminal device. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

[0054] The network device and the terminal device can be fixed in position or movable. The network device and the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on airplanes, balloons and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the network device and the terminal device.

[0055] The network device and the terminal device can communicate through an air interface protocol. The air interface can be referred to as an air interface. The network device and the network device can communicate through a network device and network device interface protocol. The terminal device and the terminal device can communicate through a terminal device and terminal device interface protocol. The network device and the terminal device, the network device and the network device, and the terminal device and the terminal device can communicate through a licensed spectrum, or through an unlicensed spectrum, or through a licensed spectrum and an unlicensed spectrum at the same time, without limitation.

[0056] The roles of the network device and the terminal device can be relative. For example, the helicopter or the unmanned aerial vehicle 120i in FIG. 1 can be configured as a mobile network device. For the terminal device 120j that accesses the wireless access network 100 through 120i, the terminal device 120i is a network device. However, for the network device 110a, 120i is a terminal device, that is, 110a and 120i communicate through a wireless air interface protocol. Of course, 110a and 120i can also communicate through a network device and network device interface protocol. In this case, 120i is also a network device relative to 110a. Therefore, the network device and the terminal device can be collectively referred to as a communication apparatus. 110a and 110b in FIG. 1 can be referred to as a communication apparatus with a network device function, and 120a-120j in FIG. 1 can be referred to as a communication apparatus with a terminal device function.

[0057] Next, the technical features related to the embodiments of the present application are introduced.

[0058] In the process of 5G mobile communication system evolving to 5G-A technology, the communication and perception integration technology is considered as one of the key technologies that can expand the business capabilities of mobile communication networks. The core idea of this communication and perception integration technology is to add perception capabilities on the mobile communication network, and build the ability to detect, track and image targets, so that the two capabilities of communication and perception are integrated in one network, and realize harmonious coexistence and mutual benefit.

[0059] The perception technology can be generally divided into two modes: single-station perception and double-station perception. In the single-station perception mode, the sending device of the perception signal and the receiving device of the echo signal of the perception signal are the same device. In other words, in the single-station perception mode, the sending device sends the perception signal and receives the echo signal of the perception signal reflected on the surface of the perception target. Therefore, the single-station perception mode can also be called self-sending and self-receiving mode without limitation. In the double-station perception mode, the sending device of the perception signal and the receiving device of the echo signal of the perception signal are two different devices. In other words, the perception station A sends the perception signal, and the echo signal of the perception signal reflected on the surface of the perception target is received by the perception station B. Therefore, the double-station perception mode can also be called A-sending and B-receiving mode. It should be pointed out that the echo signal of the perception signal is obtained by reflecting the perception signal on the surface of the perception target, and therefore, the echo signal can still be called the perception signal.

[0060] FIG. 2 exemplarily shows a schematic diagram of a perception scene to which the embodiments of the present application are applicable. Four perception scenes to which the embodiments of the present application are applicable are provided in FIG. 2, which are: a scene in which the network device A sends the perception signal and the network device B receives the echo signal, as shown in (1) of FIG. 2; a scene in which the terminal device A sends the perception signal and the terminal device B receives the echo signal, as shown in (2) of FIG. 2; a scene in which the network device A sends the perception signal and the terminal device A receives the echo signal, as shown in (3) of FIG. 2; and a scene in which the terminal device A sends the perception signal and the network device A receives the echo signal, as shown in (4) of FIG. 2. In FIG. 2, the perception target is taken as a vehicle, and the terminal device is taken as a smart phone as an example.

[0061] The perception target can also be called a target, a detected target, a perceived object, a detected object, or a perceived device, without limitation. The perception target can be various tangible objects in the environment that can reflect electromagnetic waves. For example, the perception target can be a static object such as a mountain, a forest, or a building. For another example, the perception target can also be a movable object such as a vehicle, a drone, a pedestrian, or a terminal device. The embodiments of the present application do not limit the specific implementation form of the perception target.

[0062] The measurement parameters of the perception performance can include, but are not limited to, accuracy, resolution, and the like. The accuracy can be used to describe the error between the perception result and the ideal real result. Taking distance perception as an example, the distance between the perception target and the perception device obtained by the perception signal is 6 meters, but the actual distance between the perception target and the perception device is 5 meters, and the perception error is 1 meter, that is, the accuracy is 1 meter. The resolution can be used to describe the minimum ability of the perception to distinguish two different perception targets. Taking distance perception as an example, the distance resolution is 1 meter, which means that if the distance between two perception targets is greater than or equal to 1 meter, the perception device can distinguish that there are two perception targets; if the distance between two perception targets is less than 1 meter, the perception device cannot distinguish that there are two perception targets.

[0063] At present, how to improve the perception performance is an important research direction. In view of this, the embodiments of the present application provide a communication method and device, which can obtain the processing capability of the perception receiving end device for the perception signal, and is beneficial to improve the perception performance. The method and device described in the present application are based on the same technical concept, and the implementation of the device and the method can be mutually referred to, and the repeated parts will not be described again.

[0064] The technical terms related to the embodiments of the present application will be introduced first.

The first communication device can be a network device or a component (such as a DU or an RU, etc.) in the network device; or the first communication device can also be a terminal device or a component in the terminal device.

[0066] The second communication device can send the perception signal, and / or can configure information related to the perception signal (for example, the coherent processing interval, the cross-coherent processing interval, the resource for transmitting the perception signal, the processing manner of the perception signal, or the type of the processing result of the perception signal, etc.). For example, the second communication device can be a perception sending end device. The second communication device can be a network device or a component (such as a DU or an RU, etc.) in the network device; or the second communication device can also be a terminal device or a component in the terminal device.

[0068] It should be noted that the communication device sending the sensing signal and the communication device configuring the information related to the sensing signal can be the same communication device, or can be different communication devices. For example, in (2) of FIG. 2, the communication device sending the sensing signal is the terminal device A, and the communication device configuring the information related to the sensing signal can be the terminal device A, or can be another terminal device (such as a master terminal device), or can be a network device.

[0069] It should be noted that the description of the network device and the terminal device can refer to the related content shown in FIG. 1, which will not be described here.

[0070] The time unit can be one or several symbols, or can be one or several slots, or can be one or several mini-slots, or can be one or several sub-frames, or can be one or several frames, or can be one or several sensing slots, etc. The implementation form of the time unit is not limited in the embodiments of the present application. The plurality of time units can be continuous in time, or can be discrete, which is not limited. Exemplarily, one time unit can carry (or send or receive) one sensing signal, or can carry (or send or receive) a plurality of sensing signals, which is not limited. For ease of understanding, the following description takes one time unit carrying one sensing signal as an example.

[0071] A symbol can also be referred to as a modulation symbol, a symbol group, a modulation symbol sequence, a modulation symbol stream, a modulation symbol string, or a modulation symbol set, etc. Embodiments of the present application do not limit the modulation mode of the symbol. For example, one symbol can be one orthogonal frequency division multiplexing (OFDM) symbol.

[0072] A coherent processing interval (CPI) can also be referred to as a coherent processing time, or a correlation processing interval, or a correlation processing time, etc. Embodiments of the present application do not limit the naming of the coherent processing interval. The coherent processing interval can be understood as a time period. Optionally, the coherent processing interval can be used for sensing. For example, the coherent processing interval can be understood as a time period related to sensing processing. For example, when performing sensing signal processing, the first communication device can process (for example, process the multiple sensing signals together, or coherently process the multiple sensing signals, or correlationally process the multiple sensing signals, etc.) multiple sensing signals in the coherent processing interval to obtain a coherent processing gain. Embodiments of the present application do not limit the implementation process of the first communication device processing the multiple sensing signals in the coherent processing interval. For example, one coherent processing interval can include one or more time units. For example, one coherent processing interval can include multiple continuous time units.

[0073] For example, assuming that one time unit is one time slot, and the frame structure is: DDDSU. Wherein, D represents a downlink time slot, used for downlink transmission, denoted as a D time slot; U represents an uplink time slot, used for uplink transmission, denoted as a U time slot; S represents a time slot for uplink-downlink switching, denoted as a S time slot. One coherent processing interval can include five time units (i.e., the time units occupied by one frame structure), as shown in (1) of FIG. 3; or one coherent processing interval can also include time units occupied by multiple frame structures, as shown in (2) of FIG. 3. FIG. 3 takes one coherent processing interval including one or more time units occupied by frame structures as an example, but embodiments of the present application are not limited thereto. For example, the number of time units included in one coherent processing interval can also be less than the number of time units occupied by one frame structure, or in other words, the number of time units included in one coherent processing interval can also not be an integer multiple of the number of time units occupied by one frame structure. For example, one coherent processing interval can also include four time units, or nine time units, etc. Embodiments of the present application do not limit the implementation mode of the coherent processing interval.

[0074] The coherent processing interval, which can also be referred to as a coherent processing time, or a correlation processing interval, or a correlation processing time, or the like, is not limited in naming by embodiments of the present application. Optionally, the coherent processing interval can be used for sensing. The coherent processing interval can include a plurality of coherent processing intervals. For example, the coherent processing interval includes M coherent processing intervals, where M is an integer greater than 1. For example, when performing sensing signal processing, the first communication device can jointly process sensing signals in a plurality of coherent processing intervals to obtain coherent processing gain. The plurality of coherent processing intervals are coherent processing intervals in the coherent processing interval. The implementation of the first communication device jointly processing sensing signals in a plurality of coherent processing intervals is not limited by embodiments of the present application.

[0075] In addition, the frame structure in FIG. 3 is taken as an example of DDDSU, and embodiments of the present application are not limited thereto. For example, the frame structure can also be DSUUU; or the frame structure can also be DDSUU; or the frame structure can also be DSUUU; or the frame structure can also be DDDSUDDSUU; or the frame structure can also be DDDSUUDDDD, and the like.

[0076] FIG. 4 shows a flow diagram of a communication method according to an embodiment of the present application. As shown in FIG. 4, the communication method can include the following contents.

[0077] S401: The first communication device transmits first information. For example, the first communication device transmits the first information to the second communication device.

[0078] The second communication device receives the first information. For example, the second communication device receives the first information from the first communication device.

[0079] The first information can include information of a coherent processing interval. For example, the first information can include information of a coherent processing interval supported by the first communication device. Alternatively, the first information can include information of a cross-coherent processing interval. For example, the first information can include information of a cross-coherent processing interval supported by the first communication device. Alternatively, the first information can include information of a coherent processing interval and information of a cross-coherent processing interval. For example, the first information can include information of a coherent processing interval supported by the first communication device and information of a cross-coherent processing interval supported by the first communication device.

[0080] The terms coherent processing interval, cross-coherent processing interval, first communication device, second communication device, and time unit are not repeated here, but refer to the aforementioned descriptions.

[0081] The information of the coherent processing interval and the information of the cross-coherent processing interval are described below.

[0082] (1) Information of a coherent processing interval

[0083] The information of the coherent processing interval can comprise a maximum duration of the coherent processing interval. For example, the information of the coherent processing interval comprises a maximum duration of the coherent processing interval supported by the first communication device. For example, the maximum duration of the coherent processing interval supported by the first communication device can be 1 millisecond (ms), or 5 ms, or 10 ms, etc. The embodiments of the present application do not limit the unit and implementation of the maximum duration of the coherent processing interval.

[0084] Alternatively, the information of the coherent processing interval can comprise a maximum number of time units included in the coherent processing interval. For example, the maximum number of time units included in the coherent processing interval supported by the first communication device can be 10, or 50, or 100, etc. The embodiments of the present application do not limit the implementation of the maximum number of time units included in the coherent processing interval.

[0085] Alternatively, the information of the coherent processing interval can comprise a maximum duration of the coherent processing interval and a maximum number of time units included in the coherent processing interval. The maximum duration of the coherent processing interval and the maximum number of time units included in the coherent processing interval are described above and will not be repeated. Alternatively, the maximum duration of the coherent processing interval and the maximum number of time units included in the coherent processing interval correspond to different durations, and the capability of the first communication device is to support the minimum value of the maximum duration of the coherent processing interval and the maximum number of time units included in the coherent processing interval. For example, assuming that one time unit carries one sensing symbol, the information of the coherent processing interval comprises a maximum duration of the coherent processing interval of 10 ms and a maximum number of time units included in the coherent processing interval of 50, and the sensing signal occupies 100 time units within 10 ms, then the first communication device supports coherent processing of the sensing signal on 50 time units of the 100 time units, and does not support coherent processing of the sensing signal on the 100 time units.

[0086] In a possible implementation, the first information can indicate a frequency range (for example, denoted as a first frequency range) corresponding to the information of the coherent processing interval, or the first information can indicate a subcarrier spacing (for example, denoted as a first subcarrier spacing) corresponding to the information of the coherent processing interval, or the first information can indicate both the frequency range corresponding to the information of the coherent processing interval and the subcarrier spacing corresponding to the information of the coherent processing interval. For example, the first information includes the information of the coherent processing interval, and the first information can indicate the frequency range corresponding to the information of the coherent processing interval and / or the subcarrier spacing corresponding to the information of the coherent processing interval. With the foregoing implementation, the information of the coherent processing interval supported by the first communication device can be the same or different in different frequency ranges and / or different subcarrier spacings, and the implementation is flexible. For example, for a frequency range below 6 gigahertz (GHz), the information of the coherent processing interval supported by the first communication device is information 1, for a frequency range above 6 GHz, the information of the coherent processing interval supported by the first communication device is information 2, and the information 2 is different from the information 1. For example, for a configuration with a subcarrier spacing above 30 kilohertz (kHz), the information of the coherent processing interval supported by the first communication device is information 3, and for a configuration with a subcarrier spacing below 30 kHz, the information of the coherent processing interval supported by the first communication device is information 4, and the information 4 is different from the information 3.

[0087] Exemplarily, the first communication device can further send second information. The second communication device receives the second information. The second information can indicate a frequency range (for example, denoted as a second frequency range) corresponding to the information of the coherent processing interval included in the second information and / or indicate a subcarrier spacing (for example, denoted as a second subcarrier spacing) corresponding to the information of the coherent processing interval included in the second information. The second frequency range is different from the first frequency range, or the second subcarrier spacing is different from the first subcarrier spacing, or the second frequency range is different from the first frequency range and the second subcarrier spacing is different from the first subcarrier spacing.

[0088] (2) Information across coherent processing intervals

[0089] The information across coherent processing intervals can include a maximum time length across coherent processing intervals. For example, the information across coherent processing intervals includes a maximum time length across coherent processing intervals supported by the first communication device. For example, the maximum time length across coherent processing intervals supported by the first communication device can be 10 milliseconds, or 20 milliseconds, or 30 milliseconds, and the like. The unit and implementation of the maximum time length across coherent processing intervals are not limited in the embodiments of the present application.

[0090] Alternatively, the information of the cross-coherent processing interval can comprise a maximum number of coherent processing intervals included in the cross-coherent processing interval. For example, the information of the cross-coherent processing interval can comprise a maximum number of coherent processing intervals included in the cross-coherent processing interval supported by the first communication device. For example, the maximum number of coherent processing intervals included in the cross-coherent processing interval supported by the first communication device can be 1, or 2, or 4, or 6, or 8, or 10, etc. It should be understood that the maximum number of coherent processing intervals included in the cross-coherent processing interval is 1, which means that the first communication device does not support cross-coherent processing on the sensing signal. The embodiments of the present application do not limit the implementation of the maximum number of coherent processing intervals included in the cross-coherent processing interval.

[0091] Alternatively, the information of the cross-coherent processing interval can comprise a maximum duration of the cross-coherent processing interval and a maximum number of coherent processing intervals included in the cross-coherent processing interval. Wherein, the maximum duration of the cross-coherent processing interval and the maximum number of coherent processing intervals included in the cross-coherent processing interval please refer to the foregoing content, and will not be repeated. Alternatively, the maximum duration of the cross-coherent processing interval and the maximum number of coherent processing intervals included in the cross-coherent processing interval correspond to different durations, and then the capability of the first communication device is to support the minimum value of the maximum duration of the cross-coherent processing interval and the maximum duration corresponding to the maximum number of coherent processing intervals included in the cross-coherent processing interval. The implementation process please refer to the related description of the information of the coherent processing interval comprising the maximum duration of the coherent processing interval and the maximum number of time units included in the coherent processing interval, and will not be repeated.

[0092] Alternatively, the information of the cross-coherent processing interval can comprise a maximum number of time units included in the cross-coherent processing interval, and the implementation process please refer to the maximum number of time units included in the coherent processing interval, and will not be repeated. Alternatively, the information of the cross-coherent processing interval can further comprise one or more of the following: a maximum duration of the cross-coherent processing interval, or a maximum number of coherent processing intervals included in the cross-coherent processing interval. The maximum duration of the cross-coherent processing interval and the maximum number of coherent processing intervals included in the cross-coherent processing interval please refer to the foregoing content, and will not be repeated.

[0093] In a possible implementation, the information about the coherent processing interval can further include a maximum time interval between two adjacent coherent processing intervals. For example, the information about the coherent processing interval can further include a maximum time interval between two adjacent coherent processing intervals supported by the first communication apparatus when jointly processing across the coherent processing intervals. For example, the maximum time interval between two adjacent coherent processing intervals supported by the first communication apparatus can be 5 ms, or 10 ms, or 20 ms, and the like. For example, the maximum time interval between two adjacent coherent processing intervals supported by the first communication apparatus is 10 ms, which means that the first communication apparatus cannot exceed 10 ms between two adjacent coherent processing intervals in the process of jointly processing across the coherent processing intervals. The embodiments of the present application do not limit the implementation of the maximum time interval between two adjacent coherent processing intervals.

[0094] In a possible implementation, the first information can indicate processing of the N signals within the coherent interval. Alternatively, the first information can further include first indication information, and the first indication information indicates processing of the N signals within the coherent interval. N is a positive integer. For example, the first information indicates that the first communication apparatus supports processing of the N signals within the coherent processing interval. For example, the first information indicates that the first communication apparatus supports processing of the N signals together within the coherent processing interval. For example, the first communication apparatus supports coherent processing of the N signals within the coherent interval, which is equivalent to lengthening the duration of the coherent processing interval to the duration of M coherent processing intervals. Through the above implementation, compared with the coherent processing interval, the first communication apparatus supports coherent processing of more perception signals, which can obtain more coherent processing gain and is beneficial to improving the perception performance.

[0095] The N signals can be used for perception. Optionally, the N signals can include one or more of the following: a channel state information reference signal (CSI-RS), a positioning reference signal (PRS), a physical downlink shared channel (PDSCH), or a dedicated signal for perception.

[0096] In another possible implementation manner, the first information can indicate that the signals in each coherent processing interval in the cross-coherent processing interval are first processed to obtain M measurement quantities, and then the M measurement quantities are processed. Alternatively, the second indication information can further include a second indication signal, and the second indication information indicates that the signals in each coherent processing interval in the cross-coherent processing interval are first processed to obtain M measurement quantities, and then the M measurement quantities are processed. The M measurement quantities correspond to the M coherent processing intervals in a one-to-one manner. For example, the first information indicates that the first communication apparatus supports processing the signals in each coherent processing interval in the cross-coherent processing interval to obtain M measurement quantities, and then processing the M measurement quantities. For example, the first communication apparatus supports performing coherent processing on the signals in each coherent processing interval in the cross-coherent processing interval to obtain M measurement quantities, and then performing correlation processing (for example, correcting according to the correlation between the M measurement quantities, or discarding measurement quantities with larger errors in the M measurement quantities, and the like) on the M measurement quantities. Through the above implementation manner, the first communication apparatus supports correlation processing on the measurement quantities of multiple coherent processing intervals, can obtain more coherent processing gain, and is beneficial to improving sensing performance. Moreover, compared with the implementation manner of processing the N signals in the cross-coherent processing interval together, the implementation manner has smaller dependence on storage resources and computing power. The signals in each coherent processing interval are described in the description of the N signals, and are not described herein.

[0097] In a possible implementation manner, the first information can indicate a frequency band (for example, denoted as a third frequency band) corresponding to the cross-coherent processing interval information, or the first information can indicate a subcarrier spacing (for example, denoted as a third subcarrier spacing) corresponding to the cross-coherent processing interval information, or the first information can indicate the frequency band corresponding to the cross-coherent processing interval information and the subcarrier spacing corresponding to the cross-coherent processing interval information. For example, the first information includes the cross-coherent processing interval information, and the first information can indicate the frequency band corresponding to the cross-coherent processing interval information and / or the subcarrier spacing corresponding to the cross-coherent processing interval information. Through the above implementation manner, the cross-coherent processing interval information supported by the first communication apparatus in different frequency bands and / or different subcarrier spacings can be the same or different, and the implementation manner is flexible. For example, for a frequency band below 6 GHz, the cross-coherent processing interval information supported by the first communication apparatus is information 5, for a frequency band above 6 GHz, the cross-coherent processing interval information supported by the first communication apparatus is information 6, and information 6 is different from information 5. For example, for a configuration above a 30 kHz subcarrier spacing, the cross-coherent processing interval information supported by the first communication apparatus is information 7, and for a configuration below a 30 kHz subcarrier spacing, the cross-coherent processing interval information supported by the first communication apparatus is information 8, and information 8 is different from information 7.

[0098] Exemplarily, the first communication device can further send second information. The second communication device receives the second information. The second information can indicate a frequency band (e.g., denoted as a fourth frequency band) corresponding to the information included in the second information and / or a subcarrier spacing (e.g., denoted as a fourth subcarrier spacing) corresponding to the information included in the second information. The fourth frequency band is different from the third frequency band, or the fourth subcarrier spacing is different from the third subcarrier spacing, or the fourth frequency band is different from the third frequency band and the fourth subcarrier spacing is different from the third subcarrier spacing.

[0099] Optionally, the method can further include that the second communication device sends a sensing signal according to the first information, and correspondingly, the first communication device receives the sensing signal; or the second communication device sends third information according to the first information, and correspondingly, the first communication device receives the third information; or the second communication device sends the third information and the sensing signal according to the first information, and correspondingly, the first communication device receives the third information and the sensing signal. This is not shown in FIG. 4.

[0100] For example, the second communication device can determine the number and / or type of the sensing signal to be sent in the coherent processing interval according to the information of the coherent processing interval included in the first information, and send the sensing signal. For example, the second communication device can determine the number and / or type of the sensing signal to be sent in the cross-coherent processing interval according to the information of the cross-coherent processing interval included in the first information, and send the sensing signal.

[0101] For example, the second communication device can determine the third information according to the first information, and send the third information. The third information can indicate the duration of the coherent processing interval, or indicate the number of time units included in the coherent processing interval; and / or the third information can indicate the duration of the cross-coherent processing interval, or indicate the number of coherent processing intervals included in the cross-coherent processing interval. The duration of the coherent processing interval indicated by the third information is less than or equal to the maximum duration of the coherent processing interval supported by the first communication device. The number of time units included in the coherent processing interval indicated by the third information is less than or equal to the maximum number of time units included in the coherent processing interval supported by the first communication device. The duration of the cross-coherent processing interval indicated by the third information is less than or equal to the maximum duration of the cross-coherent processing interval supported by the first communication device. The number of coherent processing intervals included in the cross-coherent processing interval indicated by the third information is less than or equal to the maximum number of coherent processing intervals included in the cross-coherent processing interval supported by the first communication device.

[0102] It should be noted that the use of the first information is not limited in the embodiments of the present application.

[0103] In the embodiments of the present application, the first information sent by the first communication device includes information of supported coherent processing intervals and / or information of supported cross-coherent processing intervals, so that other communication devices (for example, the second communication device) can determine the processing capability of the first communication device for sensing signals according to the first information, so as to be able to configure coherent processing intervals and / or cross-coherent processing intervals and the like that conform to the processing capability of the first communication device, thereby facilitating the improvement of sensing performance.

[0104] In the embodiments provided in the present application, the method provided in the embodiments of the present application is introduced from the perspective of the interaction of the plurality of communication devices (for example, the first communication device and the second communication device). The steps performed by the communication device (for example, the first communication device or the second communication device) can be implemented by different functional entities constituting the communication device. The communication device (for example, the first communication device or the second communication device) can include a hardware structure and / or a software module, and the above-mentioned functions are implemented in the form of hardware structure, software module, or hardware structure plus software module. Whether a certain function in the above-mentioned functions is implemented in the form of hardware structure, software module, or hardware structure plus software module depends on the specific application of the technical solution and the design constraint conditions.

[0126] As shown in FIG. 6, an embodiment of the present application provides a structural schematic diagram of a communication apparatus 600. The communication apparatus 600 can comprise a processor 620, which is configured to implement or support implementation of the functions of the first communication apparatus or the second communication apparatus of any method embodiment of the present application by the communication apparatus 600, and specific implementation can be referred to the detailed descriptions in the foregoing method embodiments, which will not be repeated here.

The processor 620 can comprise one or more processors, which are not limited.

[0127] It should be noted that the above-mentioned functional modules can be implemented by hardware, or implemented by combination of hardware and software, which are not limited. When the communication apparatus 600 only comprises the processor 620, the communication apparatus 600 can be a chip, or also can be a chip system.

[0128] For example, the communication apparatus 600 can be a chip system. The chip system can be composed of a chip, or can comprise a chip and other discrete devices, which are not limited.

[0129] Optionally, the communication apparatus 600 can further comprise a memory 630, which is configured to store program instructions and / or data. The memory 630 is coupled with the processor 620.

For example, when the communication apparatus is a first communication apparatus, the other devices can be a second communication apparatus, etc. The processor 620 can use the communication interface 610 to transceive data.
